Chemistry in Crime Investigation: Sodium Percarbonate Effects on Bloodstains Detection
2011
Chemistry plays a leading role in crime investigation. In the study of bloodstains, chemical reactions provide the means for the detection. All these procedures have been thoroughly studied. However, recently, a new source of error has been found: washing stains with "active oxygen" detergents abrogates presumptive and human hemoglobin tests for bloodstains (although visible). The aim of this investigation was to evaluate the ability of pure sodium percarbonate-main component of detergents-to abrogate presumptive and human hemoglobin tests. Then, a solution to this problem could be found. The results demonstrate that pure sodium percarbonate-itself-is able to abrogate all tests, as well as …
Association of Variants in the SPTLC1 Gene with Juvenile Amyotrophic Lateral Sclerosis
2021
Key Points Question What genetic variants are associated with juvenile amyotrophic lateral sclerosis (ALS)? Findings In this family-based genetic study, exome sequencing was performed in 3 patients diagnosed with juvenile ALS and failure to thrive; this identified de novo variants in SPTLC1 (p.Ala20Ser in 2 patients and p.Ser331Tyr in 1 patient). Variants in SPTLC1 are a known cause of hereditary sensory and autonomic neuropathy, type 1A, and these data extend the phenotype associated with this gene. Meaning De novo variants in the SPTLC1 gene are associated with juvenile ALS, a fatal neurological disorder.
Killing methods in Sicilian Mafia families
2019
The Sicilian Mafia is a criminal organisation founded in Sicily which is an island south of the Italian mainland in the Mediterranean Sea. Until recently, this organization was responsible for many murders and bombings. However, recently, based on the investigations known as the “Mare Nostrum” operation, the Supreme Court convicted 67 people and sent them to prison. Some defendants were found guilty of as many as 39 murders. This article reviews the forensic analysis that was used when investigating responsibility for these Mafia murders. Our review is based on the court documents and the ballistic investigations which were carried out to evaluate the reliability of “repented” or “pentiti”…

A Magnetic Resonance Imaging–Based Prediction Model for Prostate Biopsy Risk Stratification
2018
IMPORTANCE: Multiparametric magnetic resonance imaging (MRI) in conjunction with MRI–transrectal ultrasound (TRUS) fusion-guided biopsies have improved the detection of prostate cancer. It is unclear whether MRI itself adds additional value to multivariable prediction models based on clinical parameters. OBJECTIVE: To determine whether an MRI-based prediction model can reduce unnecessary biopsies in patients with suspected prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Patients underwent MRI, MRI-TRUS fusion-guided biopsy, and 12-core systematic biopsy in 1 session. The development cohort used to derive the prediction model consisted of 400 patients from 1 institution enrolled between …

A new chemical aid for criminal investigation: dyes and latent prints
2002
Criminalistics is a field in which there are many opportunities for the practical application of chemical reagents and the use of analytical methods that provide answers to enigmas at crime scenes. Common reagents in biochemical and medical test methods can be useful for criminalistics (forensic science). Dyes are one type of reagent that can be used in obtaining crime scene evidence. This work describes a new application of CI Solvent Black 3 dye in the location of latent fingerprints. The results show that CI Solvent Black 3 can be successfully applied in the location and development of recent and non-recent latent fingerprints on porous surfaces.
Transient Focal Neurological Events in Cerebral Amyloid Angiopathy and the Long-term Risk of Intracerebral Hemorrhage and Death: A Systematic Review …
2021
Importance Transient focal neurological episodes (TFNEs) are a frequently overlooked presentation of cerebral amyloid angiopathy (CAA), a condition with prognostic implications that are still not well described. Objective To perform a systematic review and meta-analysis to examine the factors associated with incident lobar intracerebral hemorrhage (ICH) and death in patients with CAA presenting with TFNEs. Data Sources A systematic review and individual participant meta-analysis including (1) a hospital-based cohort and (2) the results obtained from a systematic search performed in MEDLINE and Embase completed in December 2019. Study Selection Included studies were observational reports of …
The Influence of Systemic Hypertension on Intracranial Pressure and Edema Formation in Experimental Intracerebral Hemorrhage
1986
Systemic hypertension is not only the most frequent cause of intracerebral hemorrhage but also the most important complication of this disease. In our clinical investigation of 117 cases almost 70% of the patients suffered from systemic hypertension. Despite advances in diagnosis (Schiirmann, Dei Anang, 1980) mortality of hypertensive patients was 48%. Normotensive hemorrhages showed a better prognosis: only 31% of the patients died and 33% (17% in hypertensive patients) obtained good neurological recovery (Wallenfang et al., 1985).
